Enhancement of pulsed-dye laser ablation of arterial tissues with blood medium: effects of laser-induced shock waves.

abstract：:Asymptomatic atrial fibrillation (AF) is common and may have the same prognostic implications as symptomatic AF. Among patients receiving dual-chamber pacemakers, it is now possible to quantify asymptomatic AF accurately. Most of these episodes are of short duration, often lasting only seconds to minutes and are calle...
